LightsOn: Move to Build a City

Media
LightsOn converts your daily movement into a city-building resource: the calories you burn automatically charge your town's battery, keeping the lights on and attracting residents. Let your activity slip and the city darkens, sending people away. It's an idle city builder where your real-world steps directly fuel progression, making it ideal for anyone seeking a low-pressure game that rewards an active lifestyle.
About this game
LightsOn turns your real-world activity into a living city.
Every active calorie you burn — walking, running, working out, or just moving through your day — flows straight from Apple Health into your city's battery. Keep it charged and the lights stay on: new residents move in, the streets come alive, and your town grows. Let the battery run dry and the city goes dark — residents pack up and leave.
It's a cozy, idle city builder where YOU are the power plant.
HOW IT WORKS
• Your active energy from Apple Health charges the city automatically — no manual tracking, it just works in the background.
• Lights on → residents arrive and your town thrives.
• Battery empty → blackout, and people start to leave.
• Real workouts earn bonus credits to spend on upgrades.
• Build a factory that produces parts for bigger and better upgrades.
• Your city keeps running while you're away — come back to see how far it grew.
WHY YOU'LL LOVE IT
• A real reason to move: every step and workout has a visible payoff.
• Relaxed, no-pressure idle gameplay — perfect for short bursts.
• A charming isometric city that's entirely yours to grow.
• Clean, dark design that's easy on the eyes.
FREE & PRIVATE
• Completely free — no ads and no in-app purchases.
• No tracking and no data collection — your health data never leaves your device.
Move more, build more. How big can your city get?
